Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Sea Trial
A sea trial or trial trip is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a "shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...

In the British and American shipbuilding traditions, this event marks the beginning date of a ship's construction.

Taffeta
Taffeta (archaically spelled taffety or taffata) is a crisp, smooth, plain woven fabric made from silk, nylon, cuprammonium rayons, acetate, or polyester. The word came into Middle English via Old French and Old Italian, which borrowed the Persian word ''tāfta'' (تافته), which means "silk" or "linen cloth". As clothing, it is used in ball gowns, wedding dresses, and corsets, and in interior decoration, for curtains or wallcovering. It tends to yield a stiff cloth with a starched appearance that holds its shape better than many other fabrics and does not sag or drape. Silk taffeta is of two types: yarn-dyed and piece-dyed. Piece-dyed taffeta is often used in linings and is quite soft. Yarn-dyed taffeta is much stiffer and is often used in evening dresses. Shot silk taffeta was one of the most highly-sought forms of Byzantine silk, and may have been the fabric known as ''purpura''. Production Modern taffeta was first woven in Italy and France and until the 1950s in Japan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
